Description

The present invention provides up to two fatty acids selected from palmitic acid, oleic acid, stearic acid, linoleic acid, α-linolenic acid, γ-linolenic acid, eicosapentaenoic acid, docosahexaenoic acid, azelaic acid, and myristic acid; and palmitoylethanolamide. The invention also relates to the use of said mixtures in the treatment of inflammatory and allergic lesions.

Fatty acids are aliphatic carboxylic acids and represent almost all complex lipids and constituents of vegetable and animal fats. These compounds can be classified based on the length of the carbon chain and/or on the basis of the presence of double bonds in said chain (saturated fatty acids, unsaturated fatty acids).

In particular, some unsaturated fatty acids are considered essential. This is because they cannot be synthesized by the body and must be supplemented by the diet. In 1964, Bergstrom, Samuelsson et al. (Nutrition classics. Biochimica et Biophysica Acta 90:207-10, 1964. The enzymatic formation of prostaglandin E2 from arachidonic acid. Prostaglandins and related factors 32) demonstrated the role of lipids in inflammatory processes and other lesions. (see Non-Patent Document 1). In 1979, the first phospholipid, phosphatidylinositol, was discovered as an element that activates cellular response processes that can activate and control reactivity through messaging elements.

Thus, lipids have a variety of roles in vivo, activities that can alter the role of individual cells or alter the microenvironment, as in the response process to an inflammatory attack. including the role of acting as a chemical messenger that can determine

Essential fatty acids, such as linoleic and linolenic acids, are precursors of arachidonic acid found in membrane phospholipids (such as those in cell membranes) and the body's inflammatory response, and pain, which is common in inflammation. , various types of eicosanoids (hydroxyeicosatetraenes, prostanoids (prostaglandins, thromboxanes and prostacyclins), leukotrienes, lipoxins and resolvins).

As is known, inflammatory responses are multifaceted, characterized by the engagement of different cells of the immune system with different engagement times, such as mast cells, macrophages, basophils and/or lymphocytes. It is an intrinsic physiological response.

The first cells involved in the inflammatory process are the mast cells, which can respond within microseconds to trigger the inflammatory process. Mast cell activation results in a series of reactions followed by the release of preformed mediators contained in the mast cell cytoplasm; in rapid succession, macrophages are contacted and activated.

Biological systems are based on receptor regulation. Following stimulation with a pathogenic agent, cells express specific receptors that are saturated by self-produced mediators (ie, mediators formed by fatty acids that form the same cell's membrane). Receptor expression is the system by which cells involved in the inflammatory process subsequently "transmit" microenvironmental growth factors, interleukins, cytokines, and the like. Saturation of these receptors first reduces the degranulation of mediators within the cytoplasm of cells (mainly mast cells) involved in the inflammatory process, and then the stimulation induced by the presence of pathogenic agents is stopped. allows you to adjust up to

However, this regulatory system is exhausted at a point when continued removal of fatty acids from cell membranes damages cells. In this situation the receptor remains overexpressed and for the cell it is a degranulation signal of the mediator that triggers protective phenomena that are no longer needed.

Thus, in the absence of receptor regulation, cells degranulate everything found in the cytoplasm with consequent contact with other cells in the microenvironment, which by remaining active It is evident that it stimulates the underlying systems to cause chronic and autoimmune inflammatory diseases such as rheumatoid arthritis, multiple sclerosis and systemic lupus erythematosus.

Thus, in these pathological conditions, it is of great importance that the body is able to regulate hyperactivated inflammatory processes by forming receptor antagonists consisting of fatty acids removed from the membrane of cells.

To meet this demand, the synthesis of pro-inflammatory chemical mediators that reduce the consumption of vegetable fats and fatty meats and promote the consumption of fish and certain specific oils such as linseed oil and hemp oil. Dietary regimens have been devised to suppress. This was done because, instead of arachidonic acid, greater amounts of eicosapentaenoic acid and docosahexaenoic acid (omega-3) are believed to be absorbed into membrane phospholipids.

Nevertheless, these dietary regimens eradicate important inflammatory complaints such as rheumatoid arthritis, chronic ulcerative colitis, systemic lupus erythematosus, pelvic inflammatory disease or similar atherosclerosis. It is known that it is insufficient to do so and therefore one must resort to pharmacological treatment.

Current pharmacological treatments for inflammatory complaints include corticosteroids (such as cortisone) or NSAIDs (non-steroidal anti-inflammatory drugs), drugs that act on the arachidonic acid cascade at various levels. ).

The function of this cascade is to induce an inflammatory response, maintain it until its danger is eliminated, and then provoke an immune response until it becomes detrimental (as occurs, for example, in chronic inflammation or autoimmune diseases). is to adjust In particular, corticosteroids prevent cellular processes that lead to the synthesis of pro-inflammatory and immunostimulatory substances and activate cellular processes that lead to the synthesis of anti-inflammatory immunosuppressive substances to alleviate disease symptoms. .

The side effects of synthetic corticosteroids often depend on the fact that, in addition to anti-inflammatory/immunosuppressive effects, synthetic corticosteroids interfere with the body's homeostatic system, causing: Hypertension, water retention, hyperglycemia, potassium wasting, osteoporosis, muscular hypotropia, capillary fragility, delayed wound healing, hyperlipidemia, accumulation of fatty tissue in the face, neck and abdomen, gastroduodenum Ulcers, increased stain clots, blood changes, euphoria, and insomnia.

With long-term treatment, these agents tend to inhibit the adrenal production of similar natural hormones, thus causing adrenal insufficiency. Adrenal insufficiency presents the most serious consequences when treatment is discontinued. In addition, long-term use of corticosteroids is associated with their immunosuppressive effects that increase susceptibility to infection.

In contrast, NSAIDs interfere at different levels with the arachidonic acid cascade and inhibit the cyclooxygenases COX1 and COX2 associated with the inflammatory process. Some of the most common side effects affect the digestive system, particularly the stomach, and include pain, burning or nausea, ulceration of the gastric mucosa which may be accompanied by bleeding, skin reactions in susceptible patients ( rash, itching).

Palmitoylethanolamide is an endogenous compound belonging to the class of fatty acid starches, chemically known as N-(2-hydroxyethyl)hexadecanamide. This compound is a key factor in regulating pathways associated with inflammatory processes, particularly those associated with mast cell degranulation downgeneration and likewise itch- and pain-based processes.

Accordingly, a need is sought to identify one or more compounds for treating inflammation that can effectively block the overactivation of the inflammatory process and reduce the side effects associated with traditional treatments. ing.
